The effect Twitter and the social Web have begun to have on entertainment, journalism and other media-related industries is by now well known and much-discussed. Its impact on other areas of human culture and knowledge, however, is still emerging. For example, how does the microblogging service impact academics and scholarly communication?

That's exactly what researchers at the University of North Carolina at Chapel Hill are hoping to figure out. The team has selected a sample of faculty and non-faculty scholars at five US and UK-based universities and used Twitter's search API to find their Twitter usernames, filtering out those whose profiles did not clearly identify them and using scripts to positively identify 230 scholars.

Buying a single article from a scientific journal is usually prohibitively expensive if you are not a student or teacher at a school that subscribes to the journal. Most academic journals are available only behind these paywalls, but Deep Dyve just announced a new product that could radically change the marketplace for scientific, technical and medical articles. Until now, Deep Dyve only indexed articles and directed users to the journal's own site. Starting today, users can rent articles from Deep Dyve. Accounts start with a pay-as-you-go account, by which users are charged $0.99 to keep an article for one day, and go up to an unlimited account for $19.99 per month.
